I’ve made an app that makes it possible to schedule a post in Lemmy at an arbitrary time. It’s available at https://schedule.lemmings.world and can be used by people from any instance.
Let me know what you think!
P.S. This post is made using the app!
Edit: And it’s open source!
I think it would be useful to automate the posts for discussions following from the broadcast of a TV show, or a sports game.
